LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 370,516, datedSeptember 2'7, 1887.

Application filed March 19,1886. Serial No. 195,775. (No model.)

To aZZ whom it may concern.-

Re it known that we, Lnwrs J. Arwoon and WILLIAM F. LEWIS, of Waterbury,in the county of New Haven and State of Connectiout, have invented anImprovement in Lamp- Bfirners, of which the following is aspecification.

This improvement relates to that class of Argand lamps in which a largeflame passes IO up around the button or fiamespreader, and the wick is aflat wick passing up into the round Argand wick-tube.

Our present improvements relate to that combination of parts,hereinafter described,

I 5 whereby the burner is rendered more reliable in its actions and therisk of smoking is materially lessened.

In the drawings, Figure 1 is a vertical section of the lamp-burnercomplete. Fig. 2 is a plan of the wick-raising devices, the parts abovethe same being removed. Fig. 3 is a separate elevation of theflame-spreader and its skirt, the supporting-stem, the valve, and theinverted conical distributer. Fig. 4 is a separate section of the airdistributer and chimney-holder.

The burner base is provided with a screw, 1, adapted to fit thereservoir-collar, and from this rises the flaring air-distributor 2. The

0 Wick-tube 3 is permanently fastened at its lower end within the screw1, and the air-tube 4: is connected with the wick-tube by one or twolateral inlet-tubes, 5,that open through the airtube and wick tube,respectively. Usually,

3 5 there will be two of these lateral inlet-tubes, so that the Argandwick will be composed of two flat Wicks brought up together into theform of a cylinder between the air-tube and the wick-tube.

0 Upon the outside of the wick-tube is the shaft 7, that carries thewick raisers 6, that pass through slots in the wick-tube. Theshaft 7 issupported by the air-distributer 2 at the upper portion thereof. Thesecond wick-raisers,

4 5 10, are upon a shaft, 11, passing through and supported by theair-distributer. These wickraisers 10 act through slots in the wick-tube3 upon the wick to raiseor lower the same, and

. there is a secondary shaft, 12, passing through the air-distributerand through the strap 8, and it is provided with a pinion, 14L, gearinginto another pinion, 15, on the shaft 11. The secondary shaft is usedfor reversing the direction of rotation, so that the wicks at both sidesof the airtube may be raised byturning 5 both buttons in the samedirection. When forcing down the wicks,both buttons are turned in thesame way, but in the direction opposite to that made use of in raisingthe wicks.

It will be understood that as the wickrais- 6 ers are at opposite sidesof the wick, to raise the wick one of the wick-raisers and shafts has tobe turned in one direction and the other in the other direction. If thebutton were di-' rectly upon the shaft 11, it would often be turned thewrong way. The gear-wheels and secondaryshaft 12, with its button, allowthis shaft 12 and its button always to be rotated in the same directionas the shaft7 when raising or lowering both wicks. The wick-raising 7wheels have teeth that are at an inclination to the wheel, so as tooccupy radial positions to the air-tube where they enter the wick; hencethey act much more efficiently on the wick than the wick-raisers withteeth that are in a a plane at right angles to the wick-raiser shaft.

The flamespreader 18 is upon the upper end of the rod 19, and the lowerend of this rod 19 is received into a step or opening in the septum 16,and around the rod 19 and connected with the same is the perforateddistributer 20, preferably conical and of perforated sheet metal, andthe parts are steadied by the spider 23, around the rod 19, and withinthe conical distributer 20. This distributor 20 is not fastened to theair-tube; but it can be drawn out, together with the valve 22, by therod 19, and with it any carbonaceous matter that may have fallen intothe air-tube is removed, and the inverted conical distributer o 20,extending above the lateral inlet-tubes 5, allows the air enteringthrough the inlets 5 to equalize and pass up uniformly to the flame. Theupper end of the conical distributer 20 is sufficiently large to comeinto contact with the 5 inner surface of the air-tube, so as to besteadied thereby, and all the air to the inside of the flame is obligedto pass through the perforations of the cone, thereby equalizing thesame.

The flame-spreader 18 has a tubular socket, 24, surrounding the rod 19,and allowing for its removal, and there is a foraminous skirt, 26, thathangs from the flame-spreader, and its lower end is open andunobstructed and above the upper end of the wick, so that the currentsof air passing the air-tube enter the base of the flame and are alsoequalized by going through the foraminous skirt into the flame.

Above the air-distributer 2 is the ring 27, that surrounds the wick-tube and forms a close connection between the wick-tube and theair-distributer 2. This ring is usually soldered in place, and it holdsthe wick-raising shafts down into their notches in the airdistributer 2.

The air-distributer 28 and the spring chimney-holder 29 are preferablymade in one piece, together with the internal spring-supports,30, thatsurround the wick-tube and hold the air-distributer and chimney-holderin place upon the same, and within the chimneyholder is the cone ordeflector 31, the upper end of which surrounds the base of the flame andpreferably rises above the upper end of the wick-tube and air-tube, andthe flange of this cone rests upon the upper part of the airdistributer28 at its junction with the chimney-holder 29.

The chimney-holder, deflector, and air-distributer 28 can be lifted offthe lamp for lighting or cleaning.

We are aware that separate wick-raising shafts have been used, and thatgearing has been employed to connect these shafts; but there was not anysupplemental shaft, as in our improvement. We are also aware that aperforated cone has been used within the airtube; but its larger end wasnot in contact with the air'tube, and it was liable to become misplacedor bent, and the air to the base of the flame did not pass through theperforated cone. This is rectified in our im provement. In cases wherethe air to Argand gas-burners has passed up through a central tube intoa hollow button or deflector the action of the same is different fromthat in our improvement, because, with the perforated skirt that hangsfrom the button, the air that passes up regularly through the perforatedcone passes unobstructedly to the base of the flame, and then the supplyof air to the higher parts of the inside of the flame is properlyregulated by the perforations in the skirt.

We claim as our invention- 1. The combination, in an Argand lampburner,of an air-tube and a wick-tube, an inverted conical air-distributerwithin and filling the air-tube, a rod for the same, removable with theair-distributer from the air-tube, a removable button having a hangingperforated skirt above the wick and supported by the rod, and aremovable deflector and chimneyholder and air-distributer supportedaround the wick-tube, substantially as set forth.

2. The combination, with the Argand airtube and wick-tube, of aninverted conical perforated distributer the upper edge of which fits theinside of the air-tube, a stem or rod connected to the cone andremovable with it from the Argand burner, and a fiame-spreader at theupper end of said stem having the perforated skirt 26, substantially asspecified.
